there is no function of the aperture but there is a function of the shutter. the shutter opens and closes to a certain point, allowing light into the camera. The hole in the shutter is the aperture

Can you use Apertures in a sentence?
yes.
What is the large apertures?
it is a part of the camera
Where is it possible to learn about camera apertures?
An individual can learn about apertures in several different ways. Photography websites, such as Nikon USA, explain how to choose apertures. Other ways to learn include books on the topic and Introduction to Photography courses.
Why do astronomical telescopes have big apertures?
they have big apertures because it helps them to observe the sky better. u know wat i mean right?
Why must telescope apertures be larger than the wavelength it is detecting?
To capture the image
Which of the apertures in a clam has an in current flow?
The Ventral aperture has an incurrent flow, the Dorsal aperture has an excurrent flow.
What part of the microscope help adjust the brightness of an image?
Brightness can be changed by changing the voltage to the lamp and adjusting the condenser and diaphragm/pinhole apertures.
The numerical apertures of the condenser and low power objective lenses are 1.25 and 0.25 you are supplied with a filter that selects a wavelength of 520nm what is the limit of resolution?
346.7nm's
What would someone use apertures for?
An aperture is a hole through which light travels. An aperture can be used for different things including cameras, telescopes and microscopes to name a few.
Are the Nikon Pro Lenses worth the cost and what are the benefits of them?
More expensive lenses usually have more durable construction needed by busy pros and wider / faster apertures (e.g. f:1.4 pro lens maximum aperture vs F:3.5 in consumer lenses). The heavier construction, larger glass elements (needed to let in more light for wider apertures), and fancier coatings add greatly to the cost of professional lenses.
Why is aperture important?
Apertures perform two functions. First is to control the amount of light entering the camera through the lens. Each aperture setting has an f number i.e.; f5.6, f8 etc.. The second function of apertures to to control depth of field - the amount of sharpness in front of and behind the subject focused upon. The smaller the aperture the less sharpness in front and behind the subject becomes. A larger aperture gives a greater amount of sharpness. The f numbers come from dividing the diameter of the hole in the diaphram into the focal length of the lens. F8 hole size divides approx. 8 times into the focal length. Each aperture is equal to half or double the value of the other. In other words from F8 to F16 reduces the amount of light by half and from F8 to F5.6 increases the amount by twice. To keep the ratio of light falling onto the focal plane after setting the aperture you need to change the shutter speed to get proper exposure. Like apertures shutter speeds that stop movement have the same values when changing form one to another. Moving from 1/125th sec to 1/250 halves the light and changing from 1/60th to 1/30th doubles it. This is why apertures and shutter speeds work together. The choice of which would be governed by the subject in hand.
Which part of a light microscope fouceses light onto the spicemen through the lens?
condenser - lens system that aligns and focuses the light from the lamp onto the specimen diaphragms or pinhole apertures
